Understanding patterns of physical activity among adults can lead to targeted approaches to improve activity levels in the African population. This study aimed to determine whether age, gender, location and employment status could predict physical activity among rural and urban South African adults, and to determine the participants' risk of developing cardiovascular disease (CVD).
A cross-sectional design was conducted on 319 participants of mean age 57 ± 10.43 years. Participants were sampled using a stratified random-sampling procedure from an urban township in Langa, Western Cape Province, and a rural township in Mt Frere, Eastern Cape Province, South Africa. A researcher-generated questionnaire was used to collect sociodemographic and physical activity data. Linear regression analysis was used to test predictive relationships.
Gender and geographical location were significant predictors (p = 0.001) of physical activity. Rural participants engaged more in physical activity (91.5%) than urban participants (84.2%) and were more likely to meet the physical activity recommendations to promote cardiovascular fitness (p = 0.000). The most frequent physical activities in rural participants were walking (15.4%), household chores (18.8%) and household chores + gardening (15.4%). The most frequent physical activities in urban participants were household chores (34.2%), and household chores + walking (33.7%). In terms of duration of physical activity, rural participants spent longer periods engaging in activities lasting up to two hours (21.4%), compared to 5.9% in urban participants (p = 0.000).
Gender and geographical location were significant predictors of physical activity among black South African adults. Overall, rural adults engaged in more physical activity than urban-dwelling adults. Males also engaged in more physical activity and at a higher intensity than females. Most rural participants met the American College of Sports Medicine recommendations for cardiovascular fitness and therefore were at minimal risk for developing CVD compared to their urban counterparts.
了解成年人的身体活动模式有助于采取针对性方法提高非洲人群的活动水平。本研究旨在确定年龄、性别、地点和就业状况是否能够预测南非城乡成年人的身体活动情况,并确定参与者患心血管疾病(CVD)的风险。
对319名平均年龄为57±10.43岁的参与者进行了横断面设计。采用分层随机抽样程序从南非西开普省朗加的一个城市镇区和东开普省弗勒里山的一个农村镇区选取参与者。使用研究人员编制的问卷收集社会人口学和身体活动数据。采用线性回归分析来检验预测关系。
性别和地理位置是身体活动的显著预测因素(p = 0.001)。农村参与者比城市参与者更积极参与身体活动(91.5%对84.2%),并且更有可能达到促进心血管健康的身体活动建议水平(p = 0.000)。农村参与者最常见的身体活动是步行(15.4%)、家务劳动(18.8%)以及家务劳动+园艺(15.4%)。城市参与者最常见的身体活动是家务劳动(34.2%)以及家务劳动+步行(33.7%)。在身体活动持续时间方面,农村参与者进行长达两小时活动的时间更长(21.4%),而城市参与者为5.9%(p = 0.000)。
性别和地理位置是南非黑人成年人身体活动的显著预测因素。总体而言,农村成年人比城市成年人参与更多的身体活动。男性也比女性参与更多的身体活动且强度更高。大多数农村参与者达到了美国运动医学学会关于心血管健康的建议,因此与城市同龄人相比,患心血管疾病的风险最小。
